CATTLE GUARD.

Specification of Letters Patent. Patented 1113. 14, 1922 Application filed November 28, 1920. Serial'No; 426,017.

To all whom it may concern:

Be it known that I, CARL M. GREEN, citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Cattle Guards, of which the following is a specification.

This invention relates to a cattle guard to prevent cattle straying along a railway right-of-way from the level crossing of a road, and is designed to be applicable to the permanent way of the railway without material alteration or change from the ordinary construction of the rails laid on cross ties on the ballast or road bed.

It is also designed to be simple and cheap in construction, readily applied and as easily removed duringwinter or during repair of the road bed. It is free from movable parts that are liable to derangement.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Fig. l is a. planof the cattle guard as applied to the railway track on one side of a level crossing.

- Fig. 2 is a cross section of the same on the line 22 'in Fig. 1.

Fig. 3 is a longitudinal section on the line 3-8 1n Fig. 1.

Fig. 4: is an enlarged section of the side frames at 4:.

5 shows an alternative edge of the inclined members.

In these drawings 2 represents the rails of the track secured to the cross ties 4, and 3 the level crossing which it is desired to protect.

Between each pair of cross ties 4.- a frame is secured composed of two transverse members 5, preferably of thin sheet metal, secured together by distance members 6 to form an acute angle from the level of the road bed toward the level crossing 3. They extend from the level of the road bed to a short distance below that of the upper sides of'the rail 2 and are spiked or otherwise secured to the tie 4:, on one of which they rest with the upper edge directed toward the level crossing. They may be secured to the cross tie 4 on which they rest by spikes, or preferably lag screws 8, so as to be removable, when desired. 7

In length they extend between the flanges of the track rails and from the outer edges of each rail flange to approximately the outer end of the cross tie. The upper edges This constitutes the guard within the length of the cross ties.

Beyond the cross ties light ladder frames, composed of longitudinals 10 with inclined cross members 11 secured between them, are secured to extend the guard protection to the width of clearance within which the fences may not project. The inner sides of these ladder frames 10-11 rest on the ends of the cross ties and the outer sides are support-ed on posts 12 secured in the ground to support the frames at an angle of approximately thirty (30) degrees from the horizontal.

These frames 10-11 may be made in such lengths that two of them will extend the length of the guard on each side. They naturally rest in a stable condition between the cross ties 4 and the supports 12 provided, but may be held down thereto by hooks and staples, as shown in Fig. 2.

With this guard the, animal is prevented obtaining a footing on the cross ties, as the upper edges of the plates 5 project angularly over the upper side of the tie, and by fittin the frames 56 between the cross ties 4, am enabled to support them thereon without any extra requirement of bevelled supporting blocks.

Although the cross members 11 of the side frames are here shown of wood, they may be made of sheet metal in the same manner as the members 5 of the track. Similarly, the transverse members 5 of the track may be made of wood, in which case they will require to have their upper edges reduced in thickness, as shown in Fig. 4.

Having now particularly described my invention, I hereby declare that what I claim as'new and desire to be protected by Letters Patent, is:

A railway crossing cattle guard comprising the combination with the cross ties of a railway track, of cattle guard members located between and at the sides of the rails transversely of the same, in combination with side guards composed of longitudinals with inclined cross rails between them, one

of said longitudinals resting on the ends of 10 the cross tie on each side of the track and the other longitudinal remoyablymonnected to posts to support the cross rails at an angle of approximately thirty degrees from the horizontal.

In testimony whereof I aifix my signature.

CARL M. GREEN.
